Vehicle and method for controlling thereof

Abstract

The present disclosure relates to a vehicle and a method for controlling thereof, and more particularly to a technique for removing noise generated in a vehicle air conditioner. The vehicle may include an air conditioner, comprising: a speaker configured to output sound; a blower fan configured to blow air that is heat-exchanged in the air conditioner; an air vent configured to regulate a discharge amount of the air discharged into the vehicle; and a controller configured to sense a noise acoustic signal of the blower fan that is determined corresponding to an opening degree of the air vent, and to control the speaker to to output by generating an acoustic signal having an opposite phase to the sensed noise acoustic signal.

What is claimed is:

 a speaker configured to output sound; 
 a blower fan configured to blow air that is heat exchanged in the air conditioner; 
 an air vent configured to regulate a discharge amount of the air discharged into the vehicle; and 
 a controller configured to:
 sense a noise acoustic signal of the blower fan that is determined corresponding to an opening degree of the air vent; and 
 control the speaker to output by generating an acoustic signal having an opposite phase to the sensed noise acoustic signal. 
 
 
     
     
       2. The vehicle of  claim 1 , wherein the controller is configured to:
 determine a spring constant of the speaker that is changed based on the opening degree of the air vent. 
 
     
     
       3. The vehicle of  claim 2 , wherein the controller is configured to:
 determine a resonance frequency of the speaker that is changed based on the spring constant of the speaker. 
 
     
     
       4. The vehicle of  claim 3 , wherein the controller is configured to:
 determine an amount of current consumption of the speaker that is changed based on the resonance frequency of the speaker; and 
 determine the opening degree of the air vent based on the amount of current consumption of the speaker. 
 
     
     
       5. The vehicle of  claim 4 , wherein the controller is configured to:
 determine the spring constant of the speaker that increases corresponding to an increase in a pressure of the air when the opening degree of the air vent is less than a predetermined value; 
 determine the resonance frequency of the speaker that increases corresponding to the increased spring constant of the speaker; 
 determine the amount of current consumption of the speaker that increases corresponding to the increased resonance frequency of the speaker; and 
 determine the opening degree of the air vent corresponding to the determined amount of current consumption of the speaker. 
 
     
     
       6. The vehicle of  claim 1 , wherein the vehicle further comprises:
 a memory configured to:
 store a size of a noise acoustic signal of the speaker; and 
 store a data on the opening degree of the air vent that is determined corresponding to an amount of current consumption of the speaker. 
 
 
     
     
       7. The vehicle of  claim 1 , wherein the speaker further comprises:
 a vibrator speaker configured to:
 output a sound by vibration of a diaphragm; and 
 cancel the noise acoustic signal of the blower fan by outputting the acoustic signal. 
 
 
     
     
       8. A method of controlling a vehicle, comprising:
 controlling an opening degree of an air vent to control a discharge amount of heat-exchanged air discharged into the vehicle through a blower fan; 
 sensing a noise acoustic signal of the blower fan that is determined corresponding to the opening degree of the air vent; 
 generating an acoustic signal having an opposite phase to the sensed noise acoustic signal; and 
 controlling a speaker to output the generated acoustic signal. 
 
     
     
       9. The method of  claim 8 , wherein the method further comprises:
 determining a spring constant of the speaker that is changed based on the opening degree of the air vent. 
 
     
     
       10. The method of  claim 9 , wherein the method further comprises:
 determining a resonance frequency of the speaker that is changed based on the spring constant of the speaker. 
 
     
     
       11. The method of  claim 10 , wherein the method further comprises:
 determining an amount of current consumption of the speaker that is changed based on the resonance frequency of the speaker; and 
 determining the opening degree of the air vent based on the amount of current consumption of the speaker. 
 
     
     
       12. The method of  claim 11 , wherein the method further comprises:
 determining the spring constant of the speaker that increases corresponding to an increase in a pressure of the air when the opening degree of the air vent is less than a predetermined value; 
 determining the resonance frequency of the speaker that increased corresponding to the increased spring constant of the speaker; 
 determining the amount of current consumption of the speaker that increases corresponding to the increased resonance frequency of the speaker; and 
 determining the opening degree of the air vent corresponding to the determined amount of current consumption of the speaker. 
 
     
     
       13. The method of  claim 8 , wherein the method further comprises:
 storing a size of the noise acoustic signal of the blower fan; and 
 storing a data on the opening degree of the air vent that is determined corresponding to an amount of current consumption of the speaker. 
 
     
     
       14. The method of  claim 8 , wherein the method further comprises:
 canceling the noise acoustic signal of the blower fan by outputting the acoustic signal.
